How tracking pixels work ↦
A fun, quick dive into Facebook’s tracking pixel and how it does its thing:
I think it’s fun to see how cookies / tracking pixels are used to track you in practice, even if it’s kinda creepy! I sort of knew how this worked before but I’d never actually looked at the cookies on a tracking pixel myself or what kind of information it was sending in its query parameters exactly.
Creepy, indeed. Our browsers are the last line of defense against such creepiness. Choose yours wisely.
